Whether you’re baking for a special diet or just want to sneak some veggies into your sweets, this recipe delivers fudgy, satisfying brownies every time.
Ingredients
- 1 cup (240g) cooked and mashed sweet potato (about 1 large or 2 small sweet potatoes)
- 2 large eggs
- 1/2 cup (120ml) pure maple syrup or honey
- 1/3 cup (80ml) melted coconut oil (or unsalted butter, melted)
- 2 teaspoons pure vanilla extract
- 1/2 cup (50g) unsweetened cocoa powder
- 1/2 cup (60g) almond flour
- 1/4 teaspoon salt
- 1/2 teaspoon baking soda
- 1/2 cup (90g) chocolate chips, plus extra for topping (optional)
Instructions
- Prepare the sweet potatoes: Preheat your oven to 350°F (175°C). Pierce the sweet potatoes with a fork and bake directly on the oven rack for 45-60 minutes, or until very soft. Alternatively, peel, cube, and steam them for 15-20 minutes until fork-tender. Let cool slightly, then mash until completely smooth. Measure out 1 cup.
- Line the pan: Line an 8×8-inch (20x20cm) baking pan with parchment paper, leaving some overhang for easy removal. Lightly grease the sides if not using parchment.
- Mix wet ingredients: In a large mixing bowl, whisk together the mashed sweet potato, eggs, maple syrup (or honey), melted coconut oil, and vanilla extract until smooth and well combined.
- Add dry ingredients: Sift in the cocoa powder to avoid lumps, then add almond flour, salt, and baking soda. Stir until just combined and no dry streaks remain. The batter will be thick.
- Fold in chocolate chips: Gently fold in the chocolate chips. If desired, reserve a few for sprinkling on top.
- Transfer to pan: Spread the batter evenly into the prepared pan, smoothing the top with a spatula. Sprinkle reserved chocolate chips over the surface if using.
- Bake: Bake for 22-28 minutes, or until the center is set and a toothpick inserted comes out with moist crumbs (not wet batter). Do not overbake, as they will firm up as they cool.
- Cool and serve: Allow the brownies to cool in the pan for at least 30 minutes before lifting out and slicing. For cleanest cuts, chill in the fridge for 1 hour before slicing.
Tips
- Substitutions: Almond flour can be swapped for oat flour (use certified gluten-free if needed). For a nut-free version, try sunflower seed flour, though color may darken.
- Sweetener choices: Maple syrup and honey both work well, but agave syrup or date syrup can also be used for a different flavor profile.
- Texture matters: Be sure the sweet potato mash is completely smooth; lumps will affect the texture of your brownies. A food processor works well for this step.
- Don’t overbake: Brownies continue to set as they cool. Pull them from the oven when just set in the middle for the fudgiest result.
Serving Suggestions
- Enjoy these brownies as a snack with a glass of cold milk or a cup of coffee.
- For a decadent dessert, serve warm with a scoop of vanilla or coconut ice cream and a drizzle of melted chocolate.
- Top with a dollop of whipped cream or Greek yogurt and a sprinkle of cinnamon for a cozy touch.
- Cut into small squares for a lunchbox treat or healthy party platter.
Variations
- Vegan: Replace eggs with flax eggs (2 tablespoons ground flaxseed mixed with 5 tablespoons water; let sit 10 minutes to gel). Use dairy-free chocolate chips.
- No added sugar: Use mashed, very ripe bananas in place of some or all of the maple syrup for a less sweet, fruit-sweetened version (texture will be softer).
- Nutty brownies: Fold in 1/3 cup chopped walnuts or pecans for crunch.
- Spiced brownies: Add 1/2 teaspoon cinnamon or a pinch of cayenne for a flavor twist.
- Extra chocolatey: Swirl in 2 tablespoons of natural peanut butter or almond butter before baking for a marbled effect.
Storage and Reheating
- Room temperature: Store brownies in an airtight container at room temperature for up to 2 days.
- Refrigerator: For longer freshness, keep them in the fridge for up to 5 days; they’ll become even fudgier when chilled.
- Freezing: Brownies freeze well for up to 3 months. Slice, wrap tightly in plastic wrap, and place in a freezer-safe bag or container. Thaw overnight in the fridge or at room temperature for an hour.
- Reheating: To enjoy warm, microwave individual slices for 10-15 seconds, or reheat in a 300°F (150°C) oven for about 5 minutes.
Frequently Asked Questions
- Can I use canned sweet potato puree?
Yes, canned sweet potato puree works as long as it contains only sweet potato and no added sugars or spices. Measure out 1 cup and proceed with the recipe. - Are these brownies gluten-free?
Yes, as written with almond flour, these brownies are naturally gluten-free. If you substitute oat flour, make sure it is certified gluten-free if needed for dietary reasons. - Can I make these brownies without eggs?
Absolutely. Replace each egg with a flax egg (1 tablespoon ground flaxseed + 2.5 tablespoons water, mixed and left to gel for 10 minutes). The brownies will be a bit denser but still delicious. - What’s the best way to mash sweet potatoes?
For the smoothest texture, use a food processor or blender. If mashing by hand, be sure to cook the sweet potatoes until very soft and mash thoroughly to remove all lumps. - Can I reduce the sweetener for less sweet brownies?
Yes, you can reduce the maple syrup or honey to 1/3 cup for a less sweet brownie. You may also want to add a few tablespoons of milk or non-dairy milk to replace the lost moisture. - Why did my brownies turn out gummy or too moist?
This usually happens if the sweet potatoes are not fully cooked or well-mashed, or if the brownies were underbaked. Make sure to bake until set in the center and let them cool completely before slicing.
